What are the best dive sites around Koh Tao?

The most iconic sites accessible from Koh Tao are: Sail Rock (unanimously considered the best site in the Gulf of Thailand, with its unique chimney and large pelagic species), Southwest Pinnacle (giant anemones, sharks), Chumphon Pinnacle (barracuda schools and whale sharks), and the military wrecks HTMS Sattakut, HTMS Hanhaksattru and HTMS Suphairin. The Divers Boat runs trips to all these sites on our blue boat, dedicated exclusively to certified divers.

What certification level do I need for fun dives in Koh Tao?

To join fun dives in Koh Tao at The Divers Boat, you need at least an Open Water certification (or equivalent PADI, CMAS, FFESSM). Our blue boat is reserved exclusively for certified divers, ensuring a higher quality experience for everyone on board.

How many dives per trip and which sites are visited?

Our fun dive trips include 2 to 3 dives per day depending on the programme. The blue boat runs a fixed weekly schedule: 3S trips (Southwest Pinnacle + Sail Rock + Shark Island) three times a week, and double Sail Rock trips on other days. The full schedule is available on our fun dives page.

Can you see whale sharks in Koh Tao?

Yes! Koh Tao and the surrounding pinnacles — especially Chumphon Pinnacle and Sail Rock — are among the best places in the world to encounter whale sharks, the largest fish on the planet. Sightings are never guaranteed, but our instructors know the best spots and seasons for these incredible encounters.

Fun Dives Koh Tao — The Best of the Island Is Underwater

If you hold at least an Open Water certification, fun dives Koh Tao are among the most rewarding experiences the Gulf of Thailand has to offer. At The Divers Boat, we take certified divers to the island’s most spectacular sites every day, on a boat exclusively dedicated to fun diving. Indeed, no other centre on the island offers this level of specialisation.

Sail Rock, Southwest Pinnacle and the Island’s Military Wrecks

Whether you’re chasing whale sharks at Sail Rock or exploring the anemone fields of Southwest Pinnacle, our fun dives Koh Tao will take you there. Moreover, our staggered departure times mean you’ll arrive on site once other boats have already left. As a result, you get more space, calmer conditions, and better encounters with marine life.

What You’ll Encounter Underwater

On the fun dive menu, small marine creatures are part of the reward: nudibranches, flatworms and prawns among them. In addition, colourful reef fish are everywhere: angelfish, butterfly fish and trigger fish. Furthermore, larger pelagic species also make regular appearances: whale sharks, groupers, barracudas and stingrays.
